To alli-'whom t may] concern," z

Be it known vthat I, `WILLIAM 'P11152'Coon'v RIPPIN, a subject of Ythe Kingdom'oi'Great' t Britain, residing at Sunbreakf Desford, near Leicester, in the county 'of`Leicester,` England," have invented Improvements in or'Relating. to Dough-Molding 'and `Like Machines,of whichthe, following fis a specification. Y v 5 'This inventioncomprisesV certain provements in dough-molding f and like machines, for molding, pressing,'.and 'shaping dough or like plastic materialjinto'lumps of suitable size and shape, andisrelated to the inventionf forming subject 'of jmy prior patent No.v 71,125,399, granted-to me January19, 1915.-

The machine according to said prior patent comprises" a rotor; disposed within aA stator, the rotorubeingl formed with alower inclined portion to" form-the molding trough, and the stator beingk provided with a series' oi'-v rotatable discs carried upon lshafts mountedv radially Within thev stator,

these discs having conical or conveX'tfaces 'and serving to stretch'and turn the lumps of A dough y during their -rolling passage yaround the lannularl moldingtrough provided between'the rotor and thelstator.v According to. the present invention a dough-molding machine, of the type having a rotorr disposed within ay stator to provide an intermediate annular molding trough,lis

furnished with an annular press ram. The latter forms thestriker of the stator, is disposed within the stator body', and has a verticallyl reciprocating movement over and within the molding trough, whereby` a downward pressure is intermittently-ap# Y 4b plied to the lumps of doughV during their rolling passagearound the annularqfand downwardly tapering or curving molding trough, to thereby set up :a combined stretching, turning, folding, rol1ing, 'and V squeezing action, for lthe/"more effective molding, pressing, and shaping kof the lumps of dough.

The upper-part ofthis'xed Y underfr'ame 2l-is formed with a central vertical boss projecting upwardly anddown- Wafdly in r alignmentV with the axisl of the 7574, I

stator, and;` within this boss 3 is lrotatably mounted a bearing sleeve 4 projecting both Vfrom'the topjand` bottom of the boss, the upper prOjeCting'end of this sleevel having fixed vthereon the wheel-like `frame of the l30 rotorA 5, which is disposed concentrically within the j stator.` `Theg outer ory annular' part 6 of this yrotor ,frame is vfof substantially L-shaped cross-section, and within the exterior angle of ythis annular L-shaped part 6 is fitted theinclined portion of ther'otor, advantageously built -up :in ywooden sectorsl 7 of an upwardly andl'outwardly con'fsave` formation at '8,renewably secured in posi# .tion by means VVof arsupyerposedring'memberY 90' Vthrough the series of sectors, and through the base of the jL-'shaped rirn 6 ofthe'sr'otor; n

The lower projecting vendof the sleevefl'has 95 n' xedthereon a large bevel gear'wheel 11,v

advantageously of ka conical form, f'whichbevel wheel 11 "is geared toa bevel` pinion 12 mounted on'fa'main driving 'shaft 13,

which 'latteris 'rotatably mounted'in hori-A 10.0 j

zontal bearings 14 provided in the lower part of the underframe 2, and is fitted externally of the underfraine with fast and loose driving pulleys 15, 16. Suitable ball thrust bearings 17 and 13 are interposed between the central bearing boss 3 of the underframe 2 and the rotor 5 and its bevelled driving wheel 11 respectively.

The construction as so far described is more or less similar to that set forth in the specificationY of my aforementioned prior patent.

The stator is of a two-piece construction, comprising the annular L-shaped body meinber 1 already described, and a superposed annular press rain or striker 19 disposed. concentrically and slidably therein. This annular press ram or striker 19 comprises a central wheel-like frame part 20 and a v downward annular flange part 21 fitted loosely within the upturned part of the L-shaped body 1 of the stator, and within this downtuined flange. 21 is fitted a comple mentary annular series of wooden sectors 22, Figure 1, suitably inclined on their inner annular face 23, in opposition to the concave annular face 8 of the rotor, to complete. the annular molding trough 24 of the desired crossfsectional form. This annular series of ram sectors22 may be'renewably fixed in position by screws 25 passing through the downturned flange 21- of the annular press ram orV striker 19, or said downturned flange 21 maybe of such an iuternal configuration, see. liligure 3, as to dispense with the necessity for said sectors. The interior angle of the L-shaped body member 1 of the stator is likewise fitted lwith an annular series of woodensectors 26, renewably secured by screws 27 or` thel like, to complete the annular moldingftrough 2st lto .the desired cross-,sectional shapel at its lower reduced extremity. The wheel-like frame 20 of the annular press ram or striker 19 isforined with aI central boss 28which is fixedly'lmounted upon the reduced upper cxtreinity 29I of a central bearing shaft 30 which. extends s lidably throughthe central bearing sleeve ll, of the rotor, the lower projecting extremity of this sliding shaft 30 being apertured` transversely to receive a pin 31V which provides a connection to the upwardly projecting forked arm 32y of `au eccentric device 33 which is mountedi on an inward extensiont of the horizontal main drivingV shaft 13, this inward shaft extension` 3.4;A beingcarried in supplemental bearings35 provided on the. lower1 interior part ofthe underframe 2.

As they main driving shaft 13 is rotated thereforeto` drive the rotor 5, a vertical reciprocating movement is simultaneously imparted to the central vertical bearing shaft 30,v which vertical reciprocating movement istransmitted toT the annular press ram or striker part 19 of the stator, located slidably and concentrically over and around the annular molding trough 24. The extent of this vertical reciprocating' movement of the annular press ram or striker 19 may be of course regulated by varying the throw of the eccentric device 33 upon the main driving shaft.

The annular molding trough 24las described is provided with inlet and discharge openings 36 and 37 at adjacent points in the periphery of the stator, the inlet opening 36'being formed by cutting` away 'the annular press ram orstriker part 19 of the stator as shown at 38, and the discharge opening 37 being formed by cuttingaway as shown at 39 the upright Vperipheral part of the annular L-shapeduv body member of the stator to the desired extentto the level of the rotor base. A fixed partition block 4() having a'curved guide surface 41 on itsdischarge side is interposed.between said inlet opening 36 and. discharge opening 37.-

The rough lump of dough, fed into the annular molding trough 241m the direction ofthe arrow l2 by way of the inlet opening 36, is indicated atV 43,- Fignre 2, whilst the lump as pressed and molded in thetrough, for discharge in thedirection ofthe arrow eeby way of the discharge opening 37, is indicated at 45, Figure 1. The direction of rotation of the rotor 5 is indicated by the arrow 4:6, Figure 2.
